The present invention relates to transmission mechanisms for motorvehicles and embodies, more specifically, an improvedtransmissionconstruction, wherein the bearings for certain of the shaftsare mounted in an improved fashion to facilitate the proper positioningthereof and the easy inspection and repair thereof.

Where transmission housings are formedv the provision of an improvedtransmission housing for mounting a plurality of aligned shafts uponbearings in such fashion that the proper space and alignment of thebearings is readily effected. Y

A further object of the invention is to provide a transmission housingof the above character wherein aligned driving and driven shafts aremounted upon bearings which are positioned and properly spaced by meansof a retainer sleeve which may he separately machined and finished priorto the assembly of the parts of the transmission.

A further object of the invention is to provide an improved transmissionhousing wherein provis on is made for readily assembling the shaftswithin the housing, such operation being effected by sna-lring of theshafts through a housing structure including an aperture which isinclined with respect to the axis of the housing.

Further objects of the invention, in addition to those specificallyenumerated above will be apparent as the invention is described indetail in connection with the accompanying drawing, wherein theV singlefigure is a view in section taken through a transmissionv 1931.'Y sensiNo. 536,209.7

constructed. in accordance with the present invention, the plane of thesection-passing through the' longitudinal mission.- p i p 'lilithreference vto the above drawingV a clutch bell housing is indicated at10 to whichis secured a transmissionv housing 11 pro-y vided iwith acover 12 which maymount suitable controlling mechanism inV accordancewith well-known practice. The houslng is 'provided withl bearing rings13 and 14 for mounting the `forward bearings ofV the driving andc'ountershafts, respectively.` Bearings 15 and 16 are provided Vforjournal-Y ing the rear ends of the driven shaft and countcrshaft,respectively, these bearings being mounted in the rear wallr'of thetransmission housing 11.` I i i A countershaft 17 is journaled atitsrear extremity in the bearing 16 and at its for-I ward extremity vinja bearing 18 carried by" the ring 14. Driving shaft 19 is journaled ina gear 22, in the forward kextremity of the .transmissionhousing,v andis centered by va gear 21 which is mounted in 'amanner to be describedhereinafter.` The gear 22 is mounted over the driving shaft 19, thisgear being journaled by the bearing 20and by a second bearing 23. Upon asplined portion 24 of thekk driving shaft 19 is arsliding clu`tch'25axis of the trans-y Vwhich'engages mating clutch teeth formed on gear 22and similar teeth formed 'on gea-r'21.

Gear 21 is journaled inbearings 26 and 27 Ysa eter `as to enable itto beinserted throughy theusual apertures `formed in the endsof thetransmission housing and lan inwardly eX- tending flange or shoulder 33is formed within the sleeve and seats the bearing27, a po- Y sitioningring 34 being threaded down against the outerbearing race to positionVthe bearing properly.

The sleeve 31 is cut laway at35 and at 36 ioo 291 with and is adapted tobe secured over such to receive a gear 37 on the countershaft 17 androck shaft 38. Rock shaft 38 is provided with a suitable fork to engagethe clutch 25 in accordance with well known practice and the sleeve 31is formed with an inwardly extending annular rib 39 which providesshoulders against which the bearings 23 and 26 are seated. In thisfashion, the sleeve 31 may be finished prior to 'assembly within thetransmission housing and the bearings for the several rotating parts arethus readily and effectively mounted in the desired positions. i

In order that the countershaft 17 may be 'assembled as a unit prior toits insertion within the housing, the bottom of the latter is formedwith an aperture 40, the plane of which slopes with respect to the axisof the housing. A cover plate 41 cooperates thereaperture by means ofbolts 42, the cover thus constituting part of the bottom of the casingand one end wall. In this fashion countershaft 17 may be snaked into thehousing by 1 inserting the right hand end thereof first and moving theshaft bodily toward the right, as viewed in the drawing, until the lefthand end of the shaft clears the left end wall of the housing, at whichtime the shaft is lifted into the position shown and the bearingssecured. f

From the foregoing, it will be seen that a transmission housing has beenprovided, wherein the bearings 'are readily and effectively seated inposition and maintained in such position, the elements being of suchcharacter as to enable them to be nished easily and readily assembled.

While the invention has been vdescribed with specific reference to theaccompanying drawing, it is not to be limited, save as defined in theappended claim.

I claim as my invention:

In combination with a transmission housing and 'a bracket securedtherein, a flanged sleeve carried removably by the bracket, means tosecure the sleeve in the bracket with the flange thereof against thebracket, a plurality of spaced shoulders formed in the sleeve 'andfacing in one direction to position aligned bearings and a shoulderspaced from the rst shoulders and facing in the opposite direction, saidsleeve being formed with Van aperture to receive a transmission wear.
